AV scans every file during preparation stage, also causing massive slowdowns

It also appears that during the preparation process, PA (or DynaZip) opens the file (or does something) which causes my AV (KAV) to scan each file. Why does each file need to be opened ?

I don’t like having to disable my Real-Time AV protection so can this also be looked into please.

No files are scanned during WinZip’s preparation stage (so I assume it doesn’t open them).

This only occurs when “normal” option is disabled. When enabled, the files aren’t scanned by the AV.

Hi,

You are correct - it is definetly an DynaZip issue and Yes, we have been trying to pressure them into giving us additional option to select paths in either way, nativly. Their point of view is that what PowerArchiver uses without “normal” option selected, is what it should be there… And we can “work around” it if we want, so they are pretty happy about providing both possibilites.

Of course, we shall try to continue to pressure them into giving us another option for path storing.

I have already noticed that in some cases (single file selection, full path, for example) we are using this even if we dont need to. So we will go and tripple check if everything is as fast as we could make it possibly right now, it gets confusing when you have 12 possible combinations to work with depending on user selection.

I will also check for AV scanning, I have to check deeper before giving you more info.

Few more questions - what is your current configuration? And are you using full path as well?

thanks

Try another thing please:

-Move your folder to the 2 level deep subfolder
C:\test\realfoldertest\

• Make sure full path option is delelected/try with selected as well
• Right click on “realfoldertest” and compress it

Is that actually faster, even with “normal” path option selected?

For the DynaZip people to say the “normal” option should not be there is a load of rubbish. Whatever happened to giving the user options, especially for a software component. When you next pester them about it, can you mention the statistics for when it is enabled, and also for when it is disabled. For them to say that you can workaround it, when clearly, it can’t be worked around (unless you want to wait an age when compressing large archives), is also a load of rubbish.

It wouldn’t even be that hard for them to implement.

You can also include a link to this thread.

XP SP2 with Pentium III Mobile 1.2GHz and 512MB RAM.

I wasn’t using full path. If I choose full path, the compression starts after about 24-30 seconds, which is OK.

@spwolf:

When full path is enabled, and “normal” is either enabled or disabled, the Real-Time monitor also checks every file being added. Surely when full path is enabled, the “normal” option is ignored.

Tried it already, and no it doesn’t speed it up.

There was some work done to make this faster in 9.11.

In this specific case, complete fix/improvement will be made in 9.2, however even now you will be able to see improvements as well although it is still slow in this case no matter what. (IE in my example it went down from 26minutes to 7 minutes, and in 9.2 should be around 1-2 minutes which will be ok).

In some other cases, we have speeded it up a lot, so some people might see greater improvements.

p.s. deipotent - issue with reporting “in use” files from root folder is solved as well.

[deipotent]

Thanks for the work you’ve done on it. My test folder now takes 7 minutes before the compressions actually begins.

Please keep on pestering the DynaZip people to include support for this natively, since then you could have maximum speed during preparation.

In the meantime, I look forward to PA 9.2 for an even bigger improvement.

The problem with Anti-Virus RealTime monitor scanning all files during preparation still exists in 9.11.01. I have “normal” option enabled and full path disabled, but it still occurs when these options are disabled and enabled respectively.

I’m using KAV Personal 5.0.227 with extended databases and Real-Time protection set to Maximum.

You can download a 30 day trial version of KAV from KAspersky’s website for testing purposes.

We will see more specifics when 9.2 testing starts and since we will be changing things anyway in this situation (on how compression is done). So I will be able to tell you more what happens and why (most likely it wont anymore actually).

We will continue this discussion once testing starts since now I can only speculate things and not check them properly…

thanks,

Okey dokey…

A bit more info regarding the KAV problem:

I used Filemon (www.sysinternals.com) to see what the difference was between PA and WinZip. The result is that PA actually opens the file and closes it, which is obviously what’s causing KAV to scan the file. WinZip on the other hand only queries the files, but does not actually open it, hence KAV does not scan the file in this case.

I know PA 9.2 will be released for alpha testing soon, but thought I’d let you know about this extra info now.
